| Short description | Acacia cambagei +/- Casuarina cristata woodland on clay plains |
| Structure code | Low Open Forest |
| Description | Acacia cambagei woodland, occasionally with Casuarina cristata or A. harpophylla. A tall shrub layer commonly occurs, typically dominated by Eremophila mitchellii. Scattered low shrubs may occur. The ground layer is open and usually dominated by grasses such as Astrebla spp., Eragrostis setifolia, and Paspalidium gracile and forbs such as Sclerolaena diacantha, S. tricuspis and Atriplex lindleyi. Occurs on Cainozoic clays plains. Soils are often mosaics of deep, cracking and non-cracking clays with or without gilgai, texture-contrast soils. Not a Wetland. (BVG1M: 26a). |

| Protected areas | Narkoola NP, Culgoa Floodplain NP |
| Special values | 6.4.1: Potential habitat for near threatened and endangered species including painted honeyeater (Grantiella picta). |
| Fire management guidelines | SEASON: Various (wet season or winter). INTENSITY: Low to moderate. INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Aim to exclude fire by fuel reduction in adjacent vegetation communities where possible. Undertake partial burns when necessary to reduce fuel loads and protect against severe wildfire. Burn with high soil moisture (i.e., after rain/storms) or in winter. ISSUES: Some Acacias can be fire sensitive (A. shirleyi, A. aneura) and may be killed by high intensity fire. There is rarely enough fuel load to burn in these ecosystems. |
| Comments | 6.4.1: Extensively cleared. |
